XXX is referring to non existing controller UUID

Error

Jan 24 16:36:33 mdc1 Xsan Admin[201]: ERROR: Failover priority {\n controllerUUID = "8FBFBF76-2DC4-4918-95A0-2576B3994F64";\n enabled = 0;\n} is referring to non existing controller UUID 8FBFBF76-2DC4-4918-95A0-2576B3994F64

Background

As you may already know, sometimes things go wrong in the GUI, and the only option you have is to force quit Xsan Admin.app. While thing seem to be solved, it always leave configuration errors.
Here I removed MDC1 from Xsan to isolate an issue, promoting MACPRO6 to backup MDC for a week. But when reverting back to the original setup a week later, the MACPRO6 wasn’t happy about that. What happened is that it did revert back to client, but MDC2 didn’t write that in the conf… While this doesn’t generate any GUI error and everything seems to works normally, a lot of error are printed in cvlog.

What to do…

Locate /Library/Filesystems/Xsan/config/[VOLUME]-auxdata.plist

And remove the offending controllerUUID parameter.

<key>FailoverPriorities</key>
[snip]
<dict>
<key>controllerUUID</key>
<string>8FBFBF76-2DC4-4918-95A0-2576B3994F64</string>    
<key>enabled</key>
<false/>
</dict>

Then restart volume.
